Philips LED 75w A19 daylight white light bulb 2-Pack, front view.
We tested five of the Philips 75 Watt LED Daylight White Light Bulb for this review. So far, so good in our dining room chandelier. Indeed we hope they’ll last as long as CREE predicts that we used for several years prior. If so, then they’ll pay for themselves at least ten times over.
We’ve run these five for sixteen hours each day for a couple weeks now. This Philips bulb has run throughout much of the day, with neither flicker nor failure. Plus, it cost us only $12 for a 2-pack at Home Depot. Not the cheapest LED bulbs we’ve found, but still affordable given how many years they last.
These LED bulbs operate with SOME heating. But they don’t become nearly as hot as their 75 watt incandescent counterparts. They run even cooler than compact fluorescent lamps with similar brightness.
Plus, they operate silently, with neither buzzing, humming, hissing, nor whistling. On radios, they’re also quite quiet; generating no detectable RF or EM interference on those most susceptible AM frequencies.
Further, the common A19 form factor allows them to fit in most any light fixture that supports standard incandescent bulbs. The Philips A19 bulb format looks like the traditional Edison-style incandescent bulb in size and shape. This bulb also about mirrors an incandescent in its low weight.
Gone are those heavy metal heat sinks at the base of many older LED light bulbs. These not only made the LED bulb heavier. But they also raised the shipping costs of them due to the extra weight. But these Philips units are quite light. So, they’re cheaper to ship. This, among other factors, results in inexpensive, state-of-the-art lighting for the consumer. Way to go, Philips!
Philips makes these LED bulbs significantly more affordable than the CREE models we sampled. They are currently about half the price per bulb.
These bulbs come in 75 watt incandescent equivalent output. Note that this rating IS NOT the amount of power that this LED bulb draws from the mains. Rather, it’s the amount of incandescent lamp light output that you get from this bulb. That is around 1000 lumens light output. So this Philips LED bulb produces 75 watts of equivalent incandescent light. Yet only draws 9.5 watts. So, this bulb is much cheaper to run than the 75 watt incandescents.
Softens shadows and helps spread the light more evenly. The bulb itself lights very uniformly; no dark or bright spots on the lighted globe surface.
The radiation characteristics is very much like traditional incandescent lighting. These LED lamps spread light around in nearly equal amounts. It fans out in all directions except for right underneath the base of the bulb.
This 9.5-watt LED bulb (1000 lumens) gives more light than you get from a 75-watt incandescent light bulb (700 lumens). Yet you only pay for 9.5 watts draw!
With LEDs, so much more power goes into actual light. Less of it goes into wasteful heat. Thus, LED bulbs give off far less heat. So, these solid state bulbs can be up to 83 percent more efficient than incandescent lamps.
These bulbs have a rating of 11,000 hours average life. So if you run them for three hours each day, then they’ll last you about 10 years.
Less metal in these units, owing to the greater efficiency electronics and LEDs themselves. This also makes handling them while hot much safer. No surface on this Philips LED bulb ever gets so hot as to produce burns.
Stands up well to shocks and drops, and lasts thousands of ON hours.
You get full brightness almost instantly upon LED turn-on. Instant on, Instant off.
Humidity will not destroy these bulbs. However, we suggest not getting water in them. Avoid direct rain exposure.
We detect no perceptible flickers, no matter the ambient room temperature. No brightness fluctuations from things like air conditioners starting up. The light output here remains constant through a wide range of input voltages.
Like incandescent lighting, but not like compact fluorescent lamps, Philips LED bulbs operate efficiently even in very cold temperatures. You get full brightness even when the lit area is really cold, down to -4 degrees Fahrenheit in fact.
As incandescent and CFL bulbs run for more hours, the internal filament evaporates over that time. Then, the vaporized metal deposits on the inside of their glass envelopes. So, by the time the bulb burns out, its light output has decreased alot due to these metal deposits.
But Philips LEDs do not show this light output drop. They glow almost as brightly at the end of their lives as they did when new.
They offer a CRI of 80. So, particularly the “daylight” models serve as acceptable photography lighting.
With the lower heat output of LEDs, these bulbs attract less dust and dirt. The fine dust that does build up, does not stick as much to these bulbs due to the lower heat.
We can find no carrier waves from these bulbs on the AM radio or other medium- and long-wave radio bands.
Now Philips LED bulbs usually pay for themselves many times over throughout their entire lives. But cost of about $6 per bulb, makes the investment slightly greater than that of CFL lamps. Prices have fallen, yes. And as LEDs go more mainstream, we expect Philips prices to fall more as well. Gone are those higher single-unit prices.
This is shorter than the Ecosmart™ brand, which offers a ten year warranty. But still…, pretty good.
The color of this lamp light is definitely a bluish sort of white. But it has a hint of green or yellow-green light mixed in. Perhaps Philips wanted to simulate a cloudy afternoon day, when a bit of yellow sun reflects off of the clouds. If so, they did this handily. But we like more of the blue-sky or deep gray overcast day color.
You should properly recycle these bulbs, due to the electronics inside. Dispose of these just as you would any other electronic device. Do not just throw them out in the regular trash.
Due to the internal support electronics, these bulbs might weight a little more than a traditional incandescent bulb. However, with the minimal heat sinking, the Philips bulbs are not much heavier at all.
This line of bulbs is not compatible with any light dimmers.
Nice that Philips created an affordable yet highly energy efficient LED product. It’s now practical for the average consumer to get big savings on his electricity bill. And, they won’t have to spend so much to do it.
The bulb has a three year warranty, sub $6 price tag per unit, and is shock-resistant. So we indeed found this LED bulb quite long lasting.
Given that warranty, we fear little over accidental failure due to excessive vibration, drops, and shocks. Plus, these bulbs give a full, natural-looking daylight for most uses.
It’s awesome thus, to see LEDs finally reaching mainstream lighting markets. We’d therefore, rate the Philips LED 75w A19 Daylight White Light Bulb at 96 out of 100. Lower the price some more, Philips, and you’ll get a perfect score from us. Revolutionary lighting product!
